Servicing the Battery
The battery is located inside the chassis. See “Motherboard Component Locations” on page 21.
The battery maintains system time when the server is powered off and disconnected from AC
power. If the IPMI logs indicate a battery failure, replace the battery.
Caution - Ensure that all power is removed from the server before removing or installing
the battery. You must disconnect the power cords from the server before performing these
procedures.
